To (111717710771.iii/Ht?! concern: v i

Be it known that I, Jinn, Vi. Snannn, ol

I Il'iiladolphia, in the county ol Philadelphia.

and State of Pennsylvania, have invented 5certain new and useful Improvements in Apparatus for Registering 'llelerdwnic Calls, wvhereolthe lollowing is a specification, rel- -ercnce being had to the ac'mmpanying draw- .I v ings.

a subscribers station. 7 i i The object ol' my invention is to provide a registering device whereby the subscriber 'n1ayv independently register his calls on an instrument local to his set, but connected to indicate to the operator that such a call has been registered. a

tional drum I, having its sections internally geared. according to a well known decimal system and have digits displayed upon their peripheries arranged to indicate through slot 5, l'ormed in the casing 6, surrounding said drum,theauunber of calls registered. This registering device is secured to the base of 'the apparatus in any desired manner. Said sectional drum 4, is arranged to be intermittently rotated by the oscillatory handle 10, which normally spring pressed to the position shown in the drawings. Said handle extends from one side of a disk 12, which is mounted to rotate upon a screw Ll, threaded into a block 15, which block is in turn secured to the leg 16, of the base by means of a screw 18.

The handle 10, is normally maintained in.

the position shown in the drawing by m ans of the'spri'ng 20, having one end 21, secured in block 15, and'the other end 2 engaged by a pin 23, whichextends th roughthc disk 1;. Upon one end of a shaft 'oi'ining the axis of the sectional drum l, is secured an arm Said arm is operatively connected to dish 12, by means of a lost-motion connection. Said connection comprises a spring 26, having one end lying in a slot 25, in disk 12, and having its other end passed through a hole in the free cnd'ot' the'arm 25, and extending from said arm to form a stud 29, for a. purpose to be hereinafter set forth. Upon disk 12, is a second pin 30, adapted to engage arm .45 and act as positive drive therefor, when the handle 10, is pressed to operate the register. Said disk 12, is alsoprovided with a projeo tion 32, on periphery which acts as a stop to limit the return movement of said disk under the influence of the spring 20.

Mounted upon tliebase17, but insulated therefrom is the zig-zag or serpentine shaped llat spring 35. Said spring is shown as resting upon a strip of metal 36, which is insulated from the base 17, by the strip of insulating material 37. One end of a wire 50, which forms a portion of the shunt circuit shown in Fig. V, is soldered or otherwise socured to the metal strip 36. As at present constructed the lower end 38, of the spring 35, is clamped in position by means of a plate 39, and screw 40; said plate being insulated from said spring by the strip of insulation 41.

A wire 51, in Fig. V, shows dia rammatically the connection of the base of the device with the other side of the circuit.

The registering operation is as follows The subscriber desiring to make a call, lifts the receiver 52, from the receiver hook 53,

and, the operator having obtained connection with the party desired, requests the subscriber to register. This isaccomplished by pressing the handle 10, downward as indicated by the arrow in Fi IV, and releasing it to permit its return un er the action of the spring 20. When the handle 10, is pressed downwardly the disk 12, is caused to rotate and the spring 26, is put under tension to elevate the outer end of arm 25. This continues until the stud 29, which projects from said arm, engages the under side of the end 42, of the zig-zag spring 35, which checks the upward movement of. said arm 25, until the pin 30, on the disk 12, engages the under side of said arm and snaps the stud 29, past the end 42, of said spring 35. As the stud 29, first contacts with the under side of spring end 42, the operator hears a tick caused by this contact and'the instrument is shunted out. As the stud 29, snaps past the end 42, ofjthe spring 35, said spring is vibrated and produces a loud and distinctive signal which is transmitted and is audible in the operators receiver 55, and indicates that the proper registry has been made. Upon reieasinglsaid handle thestud 29, first contacts with t e upper side of the end 42, thus again qhunting out the instrument, and upon the further return movement said pin snaps past said end by virtue of pin 23, engaging the upper side or arm 25, and again causes the spring to vibrate and produce its distinctive s1 na IFrom the above it will be seen that each time a call is registered two electrical and two mechanical signals are produced and transmitted to the operator. By the use of a lost motion connection between the operating handle and the re ister, the subscriber cannot give the require si nal without registering his call, neither wil a call be registered without the operation of the signaling mechanism; thus the subscriber and the company owning the instrument are each protected. The downward movement of the handle 10, is limited by the stop 13, engaging the shoulder 19, on the disk-12. By continuing the downward movement of the handle 10, after the stud 29, is in engagement with the under side of spring end 42, the spring 26, is put under tension, and when the stud 29, snaps past said end 42, the arm 25', is carried far enough around to move the register one digit. If the spring end 42, were removed so that spring 26, could not be put under suflicient tension, the register could not be operated, since the stop 13, would prevent the handle 10, from rotating far enough to cause arm 25, bu move the register drum.

I do not desire to limit myself to the precise details of construction and arrangement herein set forth, as it is obvious that various modifications may be made therein without departing from the essential features of my invention.

I claim:
